When I think of what electric car UX could be, this is more of what I think of, not "one giant touchscreen" and some capacitive touch buttons

Jony Ive understands iPhone UX (a slab of glass with no buttons) does not belong in the driver's seat.

This monitor is ridiculous. So I plugged in my Quicksilver G4 and tested the limits of early 2000s VGA in 6K :D www.youtube.com/watch?v=yPQb...

I was hoping it wouldn't hit my repos, but the trickle is turning into a wave of AI-generated PRs that... all they do is suck up what little time I have available for PR review trying to see if there's anything of value in the AI-generated code. There usually isn't.

This Raspberry Pi-powered laptop plugs an upgradable Compute Module into an all-aluminum chassis. But it's launching at the worst possible time. See how it performs—and why I don't recommend it right now: www.youtube.com/watch?v=Ef70...

RAM pricing is outta hand. Downgrading my Homelab so I can afford to max out the RAM on my servers again.

Raspberry Pi is getting more expensive again—price hikes add on up to $60 to the price tag of a high-spec Pi: www.raspberrypi.com/news/more-me...

These little USB-C adapters are neat! I can get most typical project voltages through Werewolf's VFLEX power adapters, and use them as a substitute for my bench power supply—in some cases.

(Note: Werewolf sent me a couple sets to test.)

A quick demo: www.youtube.com/watch?v=j2sl...
USB-C PD ALL THE THINGS!

I'm surprised I don't see more people hacking on the RP1's functionality on the Pi 5 / CM5 / Pi 500 — here's a device tree overlay enabling full PPS pin support through RP1, including PPS echo to measure Linux kernel latency for things like timing signals: github.com/josh-blake/p...

I was tired of lugging my bench oscilloscope to my desk and other places to do quick tests... so I finally bought a FNIRSI handheld oscilloscope—and it impressed me quite a bit!

Just ordered 16 GB of RAM for $44

Feels like I won the lottery.

Only catch? It's DDR2 ECC.

Finally re-routed coax from our attic antenna to the basement rack for HDHomeRun to be there instead of the living room.

My 5 yo daughter proudly crimped her first coax F connector (with a little help ofc). She also popped on hearing protection and vacuumed up the floor lol.
